    Notebook Asus N750JV-T4069H: Power Adapter And Battery State

    Hi all,
    happy with 7 months Linux experience on old HP desktop, few days ago I deleted Windows from my brand new notebook Asus N750JV-T4069H (Intel® Core™ i7-4700HQ; Bit 64; Nvidia GeForce GT750M) and installed Xubuntu 13.10. I'm not sure but it seems to me that my problem is Xubuntu bug. If this is the case, I would be very grateful if someone can communicate the problem to the development team 'cause I get lost inside the more than complicated bug reporting procedure:


    - When power adapter is plugged in, connection is not recognized and battery state is wrong

    See https://wiki.debian.org/InstallingDe.../N750JV/Jessie - perhaps the acpi= kernel parameter will fix this issue as well.

    ORIGINAL /etc/default/grub


    GRUB_DEFAULT=0
    GRUB_HIDDEN_TIMEOUT=0
    GRUB_HIDDEN_TIMEOUT_QUIET=true
    GRUB_TIMEOUT=10
    GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX=""


    Thanks for reply
    I've tried 4 different scenarios, but nothing changes:


    GRUB_CMDLINE_LINUX="acpi= nolapic. 'acpi='"
    GRUB_CMDLINE_LINUX="'acpi='"
    GRUB_CMDLINE_LINUX=acpi= nolapic. 'acpi='
    GRUB_CMDLINE_LINUX='acpi='

    I have reinstalled Xubuntu once again. Don't know if it is of any importance, but in my computer ther'e no a single trace of Windows 8 (uefi/boot).
    During installation, everything ok with power adapter connection and battery state. After installation, problem appears again-
    Nothing changes with different acpi= kernel parameter.

    Re: Notebook Asus N750JV-T4069H: Power Adapter And Battery State

    In that case can you try a few other parameters:

    First try:
    Code:
    GRUB_CMDLINE_LINUX="acpi_osi="
    Then try:
    Code:
    GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\""
    In both cases, ensure you run:
    Code:
    sudo udpate-grub
    ...afterwards and reboot. And on each reboot, first check to see if things are working better then post back the contents of your dmesg log file in the following manner:
    Code:
    pastebinit /var/log/dmesg
    ...and post back the link that is generated.

    Hi,
    thank you once again for your assistance.
    "acpi=" and "acpi_osi=\"!Windows 2012\"" are useless, but with "acpi_osi=" we're almost there

    If I unplug the power supply, correct battery notification appears. When I connect again power adapter, notification says battery is charging but adapter not connected.

    GRUB_CMDLINE_LINUX="acpi_osi="

    pastebinit /var/log/dmesg

    cat /proc/cmdline
